IMPROVEMENT INHLOOM FOR WEA'VING HATS.

.Specification forming part of Letters Patent No. 9l,305flated June 15, 1869.

To all whom. itrm'y concern:

Be it known that I, PET-ERBROOKS, of New Haven, in the county-of New Haven and State of Connecticut, have invented a new Improve' ment inLoom for Weaving Hats; and I do herebyT declare the fol-lowing, when taken'in connection with the accompanying drawings 'and the letters of reference marked thereon,

to be a full, clear, and exact description of the same, `and which said drawings constitute part of this specification, and represent, in

Figure 1 a side view; Fig. 2, a top View;

Fig. 3, a vertical central section Figs. 4, 5,6,

illustrated in the accompanying drawings.

A is the bed-plate of Ythe machine; B, the driving-shaft, from wl'rich power is communicated to a vertical shaft, C, by means of bevely gears D D; and from the said shaft C, through p a spur-gear, C, iower is communicated to -a central vertical s aft, E,which said shaft car ries a large spur-gear, E, in the center of the machine.

E2 is a central plate, upon `which the shuttie-race E3 is arranged. F and F are the two shuttles, each shuttleixed upon a segmental gear, f, and arranged within the race, so as 'to travel around a common center. Around the plate E at convenient points are arranged-pinions G Cr, which are caused to revolve by connection with the large spur-gear El, as seen' in Fig. 3, thesaid pinions arranged relatively to the segments fin the shuttle, so that, working in the saidsegments', the shuttle lis driven around the race, a second pinion taking into the segmental gearon the shuttle before the iirst has left, thus maintaining a constant and uniform velocity of the shuttles, each of thel said shuttles ca-riiviug a bobbi-n of I the filling material.

I would here remark that, while'I represent two shuttles, I do not wish to be understood as confining myself to that number, as'a single shuttle may be used, or more, if desirable. The greater the number of shuttles the faster the loom will weave.

H and H are the holders for the warpthread guides, extending around the shuttlerace, and is here represented, eachof the holders carrying four thread-guides or healds,.a. and c, as seen in Fig. 2, the said guides or healds .being arranged vertically, as seen in Fig. 3, and each guide carrying its own particular thread. When the guides are down, as denoted in Fig. 3, then the shuttle will pass over the threads carriedby the said guides; but when any of the guides are raised, as denoted in blue, Fig. 3,the thread being denoted in broken lines, the thread is raised, so that the shuttle passes beneath such raised thread; and it is essential that the threads be so raised at the proper time to introduce new threads during the process of weaving the top or brim.

To perform this, I arrange over the central shaft, E, a hollow shaft, I, and ,over thata third vshaft, L; as seen vin Fig. 3. Y The said shaft L has power communicated toit to cause to revolve through the gear C* on the .shaft C, (see Fig. 1,) the said outer shaftcarryiug a cam-wheel, M, which has a projecting flange, e, upon the outer edge',and upon the inner edge a corresponding-projecting flange, s and upon the shaft I are xed what may be called th'e jacquard-wheels N and I, the one, N, outside the cam, and .the one, P, inside the cam', as denoted in Fig. 3, both fixed to the same shaft. The said jacquard-wheels M and I? have notches cut through their upper edge, as denoted in Figs. 5, 6, and 7. The threadguides or Ahealds a and c extend down,-the one ser., c, sol as to rest upon the surface of the.

wheel N, the other set, a, so asto rest against the beveled portion of the wheel l?, as denotedI in Fig. 3, and also seen iu Fig. 5. "In this position (Fig. 5) the cam-wheel M will revolve without in any way affecting thethread-guides;

but when the wheels'N and P are .turned so that one of thethread-guides falls ,intov the notch t, as denoted at the left in' Fig. 3,;then

the projecting ledgeon the edge of the cam- M'will catch into the notch formed in the said thread-guide, and raise the guide, as denoted in blue in said Fig. 3, the cam being formed as seen in Fig. 7, and each revolution of the cam will raise the same guides which have been let oli the wheels N and P; and, as more threads are wanted, the further turning of the wheel N will cause the other thread-guides to pass into the notches ,until all are taken, as seen in Fig. 6. Therefore, commencing at the center, all the warp-threads are fixed together, and as the shuttles revolve, only so many of the warp-threads are raised as are required at that point, new warp-threads being introduced `as the process of weaving goes on and the fabric woven expands.

From each of the shuttles an arm, 1:.,extcnds to the center, bearing against the iilling-thread, which serves the purpose of a beater in a common loom.

Each of the warp-threads passes through a tension-bar, m as seen in Fig. 3, the said bar being provide with a spring, m', which forces the bar outward, to take up the slack, as denoted in Fig. 3.

In order at the proper time to introduce the requisite warp-thread, I arrange a feedwheel, R, which is caused to revolve by any convenient connection of the driving-shaft to give it the proper velocity. the said feed-wheel being formed as seen in Figs. 4 and 8, Fig. 4 being the diagram of the circumference of the wheel, and maybe explained as follows; 1 being the point of starting at the center of the crown, four teeth, 2 3 4 5, being suicient for the formation of the top of the crown, the space between 5 and 6 forthe side of the crown, and 6, 7, and 8 for the brim.

The wheel R operates upon a lever, S, (more clearly seen in Fig. 8,) and extending up to the wheel N, as shown in Fig. 6, so that as each tooth on the wheel R operates upon the lever S it will turn the two wheels N and P by means of a pawl and ratchet, T, (seen in Figs. 5 and 6,) eachl movement being sufficient to let off one of the thread-guides, either upon the outside or inside, or both, as the two wheels N and P may be arranged so that the first movement will take in an outside thread and thel second an inside, and so on.

The wheel R being caused to revolve, the tooth 2 will throw in the first-needed threadlguides in the expansion of the crown, and so ou each successive tooth, 3 4 5, more or less, until the top of the crown is formed. Then, as no more extra threads are required to be introduced until the side or body of the hat is formed, lthe space in the .wheel R between 5 and 6 has no effect upon the wheels N and P; but when 'the crown is formed and the widening for the brim necessary, then the teeth 6 7 8 in their turn introduce the extra threads required.

The cutting of the wheel R, it will be readily seen, is to be formed and adjusted according to the form and style of the hat, the diagram, Fig. 4, being suiiicient to show the construction and adjustment.

When a hat has been thusformed, to begin again for a second hat the several threadguides or healds must be returned to their first position. To do this, the wheels N and P are dropped below the ends of the threadguides by means of a lever, W, (see Fig. 1,) upon which the-shaft I rests, and turned until, in the position in Fig. 5, the wheels are again raised, bringing all the guides once more against the surface of the wheel between the spaces t, as seen in Fig. l5.V

After the top of the crown has been formed and the body is being formed, it is necessary to carry the tp of the crown down orraise it from the path of the shuttle-threads so fast as the body is formed. To do this I arrange a follower, S, centrally over the plate E, which said plate has an opening, S, through its center, the follower S' being of .the diameter of the crown of the hat.

After the top has been formed the follower is brought down onto the fabricated top, and is forced down through the opening S', carrying with it the top of the hat, so that the body will be formed around the said follower; and when the crown has been fully formed the further movement ofthe follower is stopped, holding the crown in that position until the brim is formed; and it is thus' operated by being connected to a vertical shatt- S, which said shaft is drawn down by a revo ving nut, Si, by its connection with the operative mechanism of the machine, thrown into or out of gear at the proper time. v

Eavin g fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent is 1. The wheel N, constructed with the recesses t, and combined with the cam-wheel M Eng thread-guides c, so as to operate as speci- 2. The combination of the two wheels N and P each constructed with recesses t and camwlieel M, with the thread-guides a and c,.so as to operate substantially as specified.

3. In combination with the cam-wheels N and P, the pattern-wheel R,so as at the proper time to turn either or both the said wheels for the purpose of introducing new warp-threads 4. In combination with the threadgudes aI and c, the tension-bars m, operating as described.

5. In combination .with the shuttles and warp-thread carriers, operated as described, the follower Sl, all arranged so as to operate together, substantially as and for the purpose setforth.
